Form left to right:
_RES,VOUT,VSS,OSC,_SCE,D/C,SDIN,SCLK,VDD
Use osciloscope to check whether _RES,SCLK,SDIN are present,
they are control signals. VDD is power and VSS is ground.
All pins should have resistance to ground acsepet VOUT.
If everything is ok then the problem is a rubber or a display itself.

check if there is output voltage on LCD interface on the board(use ur manuel&meter),if ok,use other LCD to test, if problem not solve,replace the LCD connector with genue one.I just solve similar problem yesterday.
